Lung radiology is regularly done for the patients in intensive care units (ICU). Chest x-ray (CXR) consider One of the most easily imaging modalities. However, CXR may be not comfortable for critical patients as well as produce hazards of irradiation. The highly variability of quality of the CXR image make CXR interpretation difficult. To show the effect of lung ultrasound (LUS) in ICU patients and diagnose pulmonary diseases compare with chest radiography. This was a prospective study done on 60 patients has acute dyspnea transmitted to the ICU of Alzahraa University Hospital. Sonographic examination of the chest and chest radiographs done to all patients. Sixty patients included in the study with acute dyspnea, CXR and LUS was done to all the patients and then compare between two modalities for diagnosis of pulmonary diseases. Ultrasound is abed side tool useful for rapid and early diagnosis of acute dyspnea in critical ill patients. LUS represents high sensitivity and high specificity of diagnosis of chest diseases as pneumonia, pleural effusion, pneumothorax and interstitial lung diseases compared to CXR.

Background:We have conducted this study to compare between levobupivacaine and hyperbaric bupivacaine in Spinal Anesthesia (SA) for hypospedius surgery in children regarding efficacy, hemodynamics, complications incidence, number of children that needed propofol infusion and surgeon's satisfaction. Aim of Study:Study comparing between levobupivacaine and hyperbaric bupivacaine in Spinal Anesthesia (SA) for hypospadius surgery in children regarding efficacy, hemodynamics, complications incidence, number of children that needed propofol infusion and surgeon's satisfaction.

Colonoscopy is an endoscopic procedure that examines the mucosa of the large intestine and distal terminal ileum for histopathological sampling and therapeutic procedures. Aim of the work: Comparing propofol & dexmedetomidine effects as conscious sedation in colonoscopy. Methods: Forty patients of both sexes candidates for colonoscopy were randomized to (D group & P group) each one included 20 patients: D Group: Dexmedetomidine was given as an initial loading dosage of 1 µg/kg i.v over ten minutes then received propofol 0.5mg/kg, then a continuous I.V. dexmedetomidine infusion (0.2-0.8) µg/kg/h was started until the procedure completed. P Group: The intravenous loading dose of propofol 2 mg/kg was given, then a continuous infusion of propofol 25-100 µg/kg/min was started until the procedure was completed. Results: The level of sedation was assessed using the Ramsay Sedation Score (RSS) showed a significant increase in the P group (2-2) compared to the D group activity (1-2) throughout 1-hour post-operatively. After 5 min of the procedure heart rate significantly decreased in group D then it became non-significant during the remaining time. The oxygen saturation % values showed a significant reduction in the P group (mean 95.45 ± 2.70) at 5 min of the procedure then it became non-significant during all remaining time. Although Bradycardia was more significantly higher in the D group, hypotension and respiratory complications were more significant higher in the P group. Also, the endoscopist was satisfied in the D group. Conclusion: In patients undergoing colonoscopy, dexmedetomidine combined with a low dose of propofol resulted in greater conscious sedation and adequate endoscopist satisfaction than propofol alone.
